I think he just ran out of string. ;-).

Interesting to see that the drive was achieved by just reeling in cords, a
bit like spinning four large tops. It must be hard work though considering
he has to lift himself AND the copter off the ground using just his own
power.

Oddley enough the ultimate energy gained is no worse than say walking
upstairs.

The rest is wasted sue to stirring air about.

That's why the blades are so big and move so slow.

same power produces much more thrust.

Same as walking up stairs carrying a helicopter on your back presumably?

An autogiro would be more useful. The father of a childhood friend built
one in his basement. IIRC, it had both pedals and a petrol engine - it
actually flew.

yes.

So not that easy then? ;-). Amazingly the helicopter "only" weighs 55kg but
that still quite a lot to haul upstairs for over a minute.

An autogiro would be more useful. The father of a childhood friend
built one in his basement. IIRC, it had both pedals and a petrol
engine - it actually flew.

I don't think that would count as "human powered". The pedals were
presunably just a way of spinning up the big rotor from rest while the
petrol engine provided the forward thrust. Once there's enough forward
speed the main rotor just "windmills" and needs no direct power source.

Besides, we're not talking "usefulness" here, we're talking about art. ;-)

If they can't find a use for the $250,000 Sikorsky prize I'll have it.

there might not be much left once they've paid the bills ;)

I bet Sikorsky were overjoyed to see Bell Helicopter on the credits
list.

All in all an impressive feat, thanks for the heads-up Tim.

Not completely useless, they got money for it.

Huh? I've got stuff I've hauled upstairs, and left there for years.

It's the hauling that needs the power, not the keeping it there. His
problem is that he hauls it up through a few metres of air - and the air
moves away, so he has to keep doing it. All that effort is about
dealing with inefficiencies.
